Abstract
PURPOSE:To facilitate connection as a kind of a terminal equipment without applying revision to a system main body by using a timer to activate a relay in response to stop/fault of an electronic computer so as to send an alarm externally. CONSTITUTION:If no fault exists in the electronic computer, a frame for polling and selecting is sent periodically even if no sent/received data exists between the computer 1 and terminal equipments 6-1, 6-2. Thus, when the computer 1 is normal, a frame detection signal is used to reset a timer 73 in a stop alarm device 7. On the other hand, if a fault takes place in the computer 1 and the detection of the frame is interrupted, the timer 73 expires and the fault of the computer 1 is informed externally.
